90% of the time when I go to the "More..." of Entities, it is to work with the "More Options" section. The rest of the time it is to edit Indexes.

"More Options" should be open by default and "Indexes" should be the first/default tab. The "Attributes" area is not as easy to use as the "tree" under "Data", and I don't think anyone ever does anything with "Example Record" or "Advanced" (I have done stuff on this tabs less than 5 times each over the last 10 years).
